Problem solving an under dash fuse/relay box.

I mean, couldn't you just take a volt meter and test the voltage going to the relay and other parts of the box? Wiggle stuff etc. You should see 12V going into it....

And this box only controls small voltages, wipers, and such. This would not affect starting issues. Your starter issues sound like a key issue... the contacts in where the key goes is worn out.
The other electrical issues could be that too as when the key is in ACC mode this is where some items turn on (radio, lights, etc.). The signal light ... not sure. Besides the starting issue it also sounds like you have a fuse box issue..
I would start with the starting issue / key. Put a volt meter on something that activates when the key is turned to ACC and see if you can make it go on / off or is it random. Wiggle the key. There is also a 50amp ignition fuse in the fuse box i think... you should investigate that too

It controls the door sw, signals, marker lights, hazards, etc. Like the main relay it has solder issues I believe. It's a sealed unit too and very hard to get out. My battle lasted several hours on this (i did mine to add delay'd wipers). I will say this box has no relation to your AC relay / clutch issue.... that seems to be different. But the fact that you can kick this area and stuff starts working again = replace.
Stupid SRS plug..
What you are after - should replace.... i think
Ill list all my symptoms
1. battery light on dash stays on even though alt is good.
2. Car turns starter over irradicably. I have to keep turning key back and forth sometimes and eventually starter will turn(i have a manual tranny). Nothing wrong with starter or other things.
3. Dome light doesn't always work with left door opened.
4. lights on chime wasn't working but did after i cleaned some connection on fuse box some months ago.
5. Left turn signal only working up front and right turn signal works fine. All of this is intermittent and i have to bang box with foot to get this limited functionality.Last edited by zedjr10; 03-16-2023, 12:01 AM.

And I'm assuming prior when you put a volt meter on the output of the fuse it was reading low or intermittent? Vs now?

I took out box and cleaned all the connections and plugs. The erratic starter not turning over went away and the drivers side door being open and not turning on dome light went away also. So did the headlight on chime not working went away. My ac was just low on freon with a Schrader valve leak(stupid me). I still have the issue of turn signals not working. Probably the relay that i forgot to take off and clean or replace when i had the fuse box out. The batt light staying on in dash lights is still there. Not sure what is causing that. My alternator is working fine.

Ya.... you need to replace that brown box in the fuse box. Known to have issues or I should say I've seen others have issues. It controls the door sw, signals, marker lights, hazards, etc. Like the main relay it has solder issues I believe. It's a sealed unit too and very hard to get out.

It was a total pita to remove. I do have some pin corrosion on pins going to box and the connection itself. That rustic color shit that appears on car batteries(whatever it is). My ac clutch relay went out also and am wondering if i should just replace the whole relay. As i do not want to have to pull this box back out again.

Most went away, it’s not to hard to replace just take a pic of where the plugs go, even though most only fit in one way. And if I recall correctly it’s only 3 10mm bolts holding it in.Last edited by zedjr10; 07-22-2022, 02:16 PM.

btw that fuse box isn't easy to pull out. A real pita to pull those plugs out of the back with a clutch there.
